It works by placing two electrodes (or sensor) in the skin at the muscles that will be monitored.
The muscles most often used by practitioners is the frontal biofeedback (creased muscle in your forehead), masseter (jaw muscle), and trapezium (shoulder muscles are stiff when you're stressed).
This machine is used to rehabilitate patients with paralysis due to stroke.
Even when a person no longer has sensation in his limbs are paralyzed and can not move, EMG is often able to detect electrical activity in muscles.
EMG machine amplifies electrical waves emitted from the paralyzed limb. When patients become aware of it, his nervous system will stimulate muscle activity.
This will create new nerve endings to grow in muscle EMG was performed, so that the patient can return to do some movement.
EMG is more often used to relax muscle tension caused by stress. When the electrodes capture the tense muscles, the machine will give a signal, such as light-colored or sound.
This way, you can feel the muscle activity and monitor continuity and start focusing on what it's like recognizing a strained muscle.
When aware of this internal process, you will begin to recognize when tensions began to arise in everyday life.
Biofeedback training like this is useful to control the tension before it becomes worse or cause other physical problems.
EMG is often used for the treatment of headaches, back pain, neck pain, and stress-related illnesses, such as asthma and acne.
